White Screen
Turn your whole screen pure white. Use it as a fill light, to clean your screen, or as a light box for tracing. Brightness, color temperature, and a timer are all adjustable, and full screen is one click away.

Colors and images are made right in your browser. Nothing is uploaded.
A web page can't change your backlight, so this slider dims the white instead. For maximum light, turn your device brightness all the way up.
What can you use a white screen for?
- Video calls and streaming: Put a second monitor or a tablet in front of your face and open the white screen. Your face will look much brighter.
- Makeup and selfies: Set the color temperature to about 5000 K, which is closest to daylight, so colors look true.
- Cleaning your screen: Dust and smudges are easiest to spot on white. Turn on cleaning mode so wiping doesn't click anything.
- Tracing: Open the white screen on a tablet with the brightness all the way up, and you have a simple light box.
- Checking your display: White shows dark spots and uneven brightness. For a full check, use the dead pixel test.
Brightness and color temperature
Lower color temperatures look warmer and more yellow; higher ones look cooler and bluer. 6500 K is the standard white on most screens. Around 3000 K is easier on the eyes at night, and 5000 to 5500 K works well for photos and makeup.
A web page can only change colors, not the backlight. For a bright fill light, turn your device brightness all the way up first, then fine-tune with the slider here.
How to use it
- Pick a mode, set the brightness and color temperature, and add a timer if you need one.
- Click Full screen, press F, or double-click the preview.
- Press Esc to exit. On a phone, tap the screen to bring up the controls, then tap Exit.
Safari on iPhone doesn't support full screen for web pages, so the color fills the browser window instead. To hide the address bar completely, add this page to your Home Screen first.
